Answer:
The team scored 96 goals during the two seasons
Explanation:
Let take Peter goal for the second season as x
And take Peter goal for the first season as y
And take the goal scored by the whole team for the two seasons as z
So.
X = 15 goals
Y = 15 - 6 goals
Y = 9goals
Z = 4(x+y)
Z = 4( 15 + 9)
Z = 4 (24)
Z = 96
Therefore the goal scored by the whole team for the two seasons is 96goals
